23 new regulations have been introduced for environmental monitoring! Implemented from July 1st, 2025
Time：
2025-02-14
The Ministry of Ecology and Environment has released 23 national ecological environment standards, covering areas such as exhaust gas, air, noise, water quality, etc. 17 of them are first-time releases and 6 are revisions. They will be implemented from July 1, 2025, further improving China's ecological environment monitoring standard system.
In order to standardize ecological environment monitoring work, the Ministry of Ecology and Environment recently issued 23 national ecological environment standards, including the "Determination of Hydrogen Sulfide in Fixed Pollution Source Waste Gas - Methylene Blue Spectrometric Method", adding another tool to China's environmental monitoring work!
It is understood that 17 of the standards released this time are first-time releases, and 6 standards are revised replacements. These standards cover multiple fields such as fixed pollution source exhaust gas, ambient air and exhaust gas, construction noise, and water quality, further improving China's ecological environment monitoring standard system. The standards will be implemented from July 1st.
Announcement on the release of 23 national ecological and environmental standards, including the "Determination of Hydrogen Sulfide in Fixed Pollution Source Waste Gas by Methylene Blue Spectrophotometry"
